“Sleep duration is not a good measure to analyze whether we are getting enough sleep or not“Torbjörn Aakerstedt, a Stockholm University neurological researcher and stress specialist, told AFP.”All this is conditioned by genes and depends on age and state of health“, he added.
Human beings would therefore be conditioned to recover well or badly whatever the length of their night. These results were achieved from three studies that analyzed the sleep patterns of 6,000 people.
According to the researchers, a 6:55 night’s sleep would be enough to feel fit and dynamic during the day. Young adults would need eight hours of sleep. Indeed, “people over the age of 20 can sleep even more, while still feeling tired during the day because their brains are still developing»Explains Aakerstedt. Seniors can be satisfied with a 6-hour night.
While sleeping more does not necessarily give more energy, sleep disorders or deprivation, on the other hand, have consequences on health: weakening of the immune system, increased risk of cardiovascular disease and type 2 diabetes, weight gain or an increased risk of road or work accidents.
